Heading toward the next-generation intelligent optical device, meta-optics active tunability is one of most desirable properties to expand its versatility beyond traditional devices. Despite advances via various tunable approaches, encoding freedom tuning capability still critically restricts widespread engagement and dynamics in real-life applications. Here, we present a gesture-interactive scheme by topography flexible metasurfaces (TFMs) for capability. Through regulating different surface topographies, potential degree (DoF) has been fully explored dynamically display/encrypt up 16 independent holographic images, exceeding state-of-the-art DoF. Such flexibility interactively tuned with gesture triggers, manual bending, other large-area repeatable controlling methods extract display respective images. We envision that this research stimulates meta-device innovation suggests applications interactive displays, information storage encryption, wearable

Optical phase imaging has become a pivotal tool in biomedical research, enabling label-free visualization of transparent specimens. Traditional optical techniques, such as Zernike contrast and differential interference microscopy, fall short providing quantitative information. Digital holographic microscopy (DHM) addresses this limitation by offering precise measurements; however, off-axis configurations, particularly Mach-Zehnder Michelson-based setups, are often hindered environmental susceptibility bulky components due to their separate reference object beam paths. In work, we have developed meta-based interferometric system using common-path DHM configuration. A meta-biprism, featuring two opposite gradient phases created GaN nanopillars selected for low loss durability, serves compact efficient splitter. Our effectively captures the complex wavefronts samples, retrieval information, which demonstrate standard resolution targets human lung cell lines. Additionally, our exhibits enhanced temporal stability compared conventional reducing fluctuations over extended measurement periods. These results not only underline potential metasurfaces advancing capabilities but also promise significant advancements diagnostics.

Metasurfaces provide an ultrathin platform for compact, real-time polarimetry. However, their applications in polychromatic scenes are restricted by narrow operating bandwidths that causes spectral information loss. Here, we demonstrate full-color polarization imaging using achromatic polarimeter consisting of four polarization-dependent metalenses. Leveraging intelligent design scheme, achieve effective arbitrary phase compensation and multiobjective matching with a limited database. This system provides broadband achromaticity across wavelengths from 450 to 650 nm, resulting relative bandwidth approximately 0.364 full Stokes imaging. Experimental reconstruction errors 450, 550, nm 7.5%, 5.9%, 3.8%, respectively. Performance is evaluated based on both crosstalk, our achieving three times the performance current state-of-the-art. The full-color, full-polarization capability device further validated customized object. proposed scheme advances practical applications.

Abstract Metasurfaces are widely applied in various applications, such as none‐line‐of‐sight detection, radar imaging enhancement, and non‐invasive monitoring. However, electromagnetic (EM) information recovery inaccessible occluded areas is of great importance to obtain complete EM picture, albeit challenging. Conventional methods this end typically necessitate specific prior knowledge suffer from performance degradation due implicit computation mechanism. Here a flow‐based framework proposed facilitate the explicit conditional distribution between partially accessible field field. The adjacent distributions hierarchical architecture exhibit similarity seamless convertibility each other, facilitating smooth transition without degradation. method benchmarked through two typical scenarios, i.e., resolution enhancement randomly areas. Even an entirely unseen scene, maintains consistence with ground truth, maximum error below 10%. work provides key advance for complex real‐world environment, offering fresh insights on access detection even extreme cases.
